FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: immunoprecipitation2.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

C57BL/6 mouse splenocytes were stained

C57BL/6 mouse splenocytes were stained with Qa-2 (clone 695H1-9-9) FITC (filled histogram) or mouse IgG2a FITC isotype control (open histogram).


Mouse Qa-2 is a 40 kD GPI-linked surface protein. It is a member of nonclassical MHC class Ib molecule encoded by Q5, Q6, Q7, Q9, and Q10 genes of the H-2 complex. Qa-2 is a nonpolymorphic molecule primarily expressed on mouse T and B cells. The expression level of Qa-2 on mature T cells is higher than on B cells. Different mouse strains express Qa-2 at varying levels. Qa-2, in association with β2-microglobulin, binds to peptide and plays a role in antigen presentation.
